(Reuters) - Stan Wawrinka, seeking his first title since undergoing two knee surgeries in 2017, subdued Canadian 10th seed Denis Shapovalov 6-4 7-6(4) on Friday to set up an intriguing semi-final with top seed Kei Nishikori at the ABN AMRO World Tennis Tournament.

The Swiss wildcard broke for a 5-4 lead in the opening set and sealed the win in a well-mastered tiebreak.

“Physically I feel really good, and I’m moving and feeling better match after match,” said Wawrinka.

“Tonight was a tough match. I had to really fight at the end. I was a bit nervous at the end of the match. We had some long rallies. It’s good to see that I can keep being there, mentally, physically.”

Nishikori took a step closer to claiming his second title of the year by defeating Hungary’s Marton Fucsovics 6-3 6-2.
